Secondary Flow in Estuaries Due to the Curvature of the Main Flow and to the Rotation of the Earth and Its Development

摘要

In tidal channels the flow pattern has a dominant influence on the morphology of an alluvial bottom. To predict bottom changes as caused by the flow a detailed description of the flow is necessary. In particular the deviations from the main flow, the so-called secondary flow, are important, as they give rise to bottom slopes transverse to the main flow. In this report the secondary flow as typical for estuaries as the Eastern Scheldt is considered.
